JELD-WEN JMI001 Premium Pocket Windows - Manual

MEASUREMENT GUIDE
for Premium Pocket Windows (JMI001)
Thank you for choosing a JELD-WEN Premium Wood or Clad Wood Pocket Window. Please read this document fully before beginning. Consult your
local building code official for applicable codes and regulations (particularly regarding minimum egress requirements). The installation of a pocket
(replacement) window will not eliminate installation or maintenance problems with an existing window. Problems such as wood decay and water
leaks around the existing frame must be investigated and fixed prior to installing a pocket window. Windows produced to user specified dimensions
cannot be returned. Be sure the provided measurements are correct.
• The existing frame jamb depth (“pocket”) must be 3 1/4" or greater for all
windows except the casement, which requires at least a 4" pocket.
• Wood double-hung pocket windows only fit on an 8° or larger sloped sill.
• If the existing window sill is not level, or if the existing window is not
square and plumb, installation may be complicated and additional trim
work may be needed during installation. Consider professional installation
assistance.
• Use the worksheet on the back to record measurements for each window
to be replaced. Use additional copies as needed for more windows.
• Record each window’s location in the house on the worksheet in a manner
that clearly identifies it.
• If there is more than 1/8" deviation within each set of measurements,
investigate the cause and seek professional assistance to correct problems.
• Perform all measurements on each window before going to the next
window.
• Individually measure each existing window to be replaced. Do not assume
similar looking windows are exactly the same size.
• Measure accurately, to the nearest 1/8".
• If a group of windows on one wall are all very similar in height, consider
using the smallest height measurement for all windows in the group. This
will maintain a pleasing appearance. This choice however could result in
additional trim work on installation.
Note! Measuring an existing sloped-sill picture or transom window for
replacement is more difficult but the goal is the same. Measure the width
between the side jambs, not including any stops/trim (wood-to-wood).
Measure the height from the true sill to the head of the window. Partial
disassembly of the existing window may be necessary. Due to the difficulty in
measuring correctly, professional assistance is recommended.
IMPORTANT INFORMATION
• Measure the width between
the side jambs (wood surface to
wood surface) in three places:
top, middle and bottom.
• Temporarily remove jamb
liners if necessary and avoid
any stops, weatherstrip,
balance cords, pulleys, etc.
• Record your measurements.
MEASURE THE WIDTH
1
CONFIRM SQUARENESS
OF EXISTING WINDOW 3
• Confirm the existing
window is square by
measuring both diagonals.
If the two diagonal
measurements differ by
more than 1/4", an out-of-
square adjustment in the
width of the window must
be made.
• The adjustment is
determined by creating
a plumb line (using a
level) from each corner to
the sill or head. Using a
plumb line that falls within
the window opening,
measure the out of square
adjustment.
• Subtract this measurement
from the smallest width
measurement. Record
this adjusted width as the
smallest width.
MEASURE THE HEIGHT
2
• Measure the height from the
head to the sill in three places:
left side, middle and right side.
• At the head, measure
directly from the wood
header avoiding any stops,
weatherstrip and liners.
• At the sill, measure on the
exterior side directly next to
the sill stop at the highest
point of the sloped sill.
• Record your measurements.
